我正在尝试使用 Firefox 在 Amazon Linux 上运行 nodeJs (node v 8.8.1) 自动化测试。由于 Amazon Linux 的一些限制，实际运行的最新版本的 firefox taht 是 41。下面是我的 Firefox 和 Amazon 版本...

[myuser@mymachine ~]$ firefox -v
Mozilla Firefox 41.0
[myuser@mymachine ~]$ uname -a
Linux ip-33-22-3-77 4.9.51-10.52.amzn1.x86_64 #1 SMP Fri Sep 29 01:16:19 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

我的问题是，我使用哪个版本的 Geckodriver 与此版本的 Firefox 兼容？使用最新版本，我们在尝试生成 Firefox 窗口时遇到错误，并且路径中没有壁虎驱动程序，我们会收到错误

编辑：根据答案，我删除并重新安装了 Selenium 2.53 驱动程序...

npm uninstall selenium-webdriver
npm install selenium-webdriver@2.53

但现在我遇到了一个新错误......

我认为，您收到该错误是因为它要求geckodriver.exe. Geckodriver 在0.8.0 版本之前最初被称为 wires 。请在您的系统路径上提供 exe。

您可以通过将此属性设置为 false 来使用 selenium 3（我认为这是最好的选择，因为它是最新的）而不提供壁虎（早期的 FF 版本）

System.setProperty("webdriver.firefox.marionette", "false");

或者做

FirefoxOptions options = new FirefoxOptions()
  .setLegacy(true);

您可能需要寻找 nodejs 等效项。

编辑： 这里是 js 版本

let options = new firefox.Options().useGeckoDriver(false);

当您执行上述操作时，FF 将使用其旧版扩展而不是 gecko

正如这里提到的

由于firefox版本是41，使用selenium 2很好，如果我们使用selenium 3意味着最新，我们需要不支持这个旧版本的gecko。

我正在使用 selenium 2，因为它具有 firefox 依赖项http://selenium-release.storage.googleapis.com/index.html?path=2.53/以及最新的 chrome 和 IE 驱动程序，以使用最新的 chrome 和 IE 浏览器。

事实证明，Amazon Linux Firefox 41 的正确版本是 selenium-webdriver 2.50，不多不少（尝试了 2.48 和 2.53，但都失败了）。
